I would like to be able to use the tab key to move between fields on the screen. For example, from the provider, to the amounts, to the value code boxes on the value screen, but the request isn't limited to that one page. Given that we've been using computers for 40 years now and this was a basic feature of Needles, this seems fundamental and certainly doable using 40 year old technology that has been proven to be efficient over time.
